Gigi

Gigi (voiced by Debi Mae West) is a recurring character, first appearing as a trainer in a gym. She is based on the character Gravity Girl (hence the name: G.G.= Gigi) from the original Birdman and the Galaxy Trio. Gigi appeared during the "Birdman Coast to Coast" special of Space Ghost Coast to Coast, as Birdman's divorced wife.

Gigi is largely defined by her shameless attitude and outlook on sex and men. She has at least ten husbands and frequently philanders with practically all male characters on the show except for Harvey (despite him being one of her husbands), claiming she "does not believe in divorce." She takes advantage of Harvey for his money and usually calls him "Harry" or "Henry." The slightest questioning of her sexual escapades, or so little as when she doesn't get her way, often send her into a crying fit while shaming the character in question. Her Galaxy Trio team-mates Vapor Man and Meteor Man have occasional cameos as her current/former casual boyfriends, Vince and Terry.

Gigi was at one point impregnated, and was quick to label Harvey as the father, despite the two having never had sex. She used this as another form of leverage for getting Harvey's money, until DNA testing suspiciously proved that the father of Gigi's child was in fact Grape Ape. Gigi appeared no longer pregnant immediately afterwards, but a child was never seen following.

Gigi makes a major appearance in the first case, "The Burning Question". She testifies that she saw Peter Potamus starting the fire that burned down Harvey's duplex. In testifying, she admitted she was Harvey's wife, which surprised him and that it was on record. However, evidence was revealed to show that Gigi actually started the fire only for insurance reasons because when they were married, Gigi signed an insurance form that entitles her to half of whatever "Harry" Birdman owns which Birdman proudly states is not his name.
